 *
	D constrains integral types to specific sizes. But efficiency
	of different sizes varies from machine to machine,
	pointer sizes vary, and the maximum integer size varies.
	<b>stdint</b> offers a portable way of trading off size
	vs efficiency, in a manner compatible with the <tt>stdint.h</tt>
	definitions in C.

	The exact aliases are types of exactly the specified number of bits.
	The at least aliases are at least the specified number of bits
	large, and can be larger.
	The fast aliases are the fastest integral type supported by the
	processor that is at least as wide as the specified number of bits.

	The aliases are:

	The ptr aliases are integral types guaranteed to be large enough
	to hold a pointer without losing bits:

	<table border=1 cellspacing=0 cellpadding=5>
	<th>Alias
	<th>Description
	<tr>
	<td>intptr_t
	<td>signed integral type large enough to hold a pointer
	<tr>
	<td>uintptr_t
	<td>unsigned integral type large enough to hold a pointer
	</table>

	The max aliases are the largest integral types:

	<table border=1 cellspacing=0 cellpadding=5>
	<th>Alias
	<th>Description
	<tr>
	<td>intmax_t
	<td>the largest signed integral type
	<tr>
	<td>uintmax_t
	<td>the largest unsigned integral type
